SNOW- PLOW.

SPECIFICATION forming part of Letters Patent No. 424,616, dated April 1,1890.

Application filed March 11,1889. Serial No. 302,919- (No model.)

To all whom it may concern.-

Be it known that I, IRVING OSGOOD, of Ellsworth, in the county ofHancock and State of Maine, have invented certain new and usefulImprovements in Snow-Flows for Sidewalks,

Roads, &c.; and I do hereby declare that the following is such a full,clear, and exact description of the invention that it will enable othersskilled in the art to which it appertains to make and use the same,reference being had to accompanying drawings, forming a part of thisspecification, in which Figure lrepresents a perspective view of myimproved snow-plow, the side 17 being partly broken away to show thewheels and interior construction. Fig. 2 is a perspective View of theguide-whee1s with their axle and attached arms.

Similar letters of reference refer to correspondingly like partsthroughoutboth figures.

The object of my invention is to produce a new and improved snow-plowfor breaking out sid ewalks, roads, and other purposes, constructed insuch mannerthat it can be easily and quickly adjusted to cast all snowupon one, both, or either side, and reversed at any time at the will ofthe operator.

Referring to the drawings, a represents a V-shaped plow constructed fromwood or other material, to the desired height, and provided at its rearportion with a cross-bar 7.", rigidly fastened to the side pieces andsuitably braced to resist the strain. Pivotod to the upper and centralportion of the cross-bar 7c is the longitudinal draw-bar 1), extendingforward over the end of the plow a and attached at its free end at thepoint marked 0 to the thills or draft-pole, which are so confined as toallow vertical movement, and prevented from side or lateral motion bythe braces d and d, as shown in Fig. 1 of the drawings.

. The draw-bar b is allowed to play over and either side of the forwardend. of the plow a, and it is held fixed in the position desired by agage-bar e, pivoted by one end at or near the upper point of the plow,and its opposite or remaining end constructed. to engage with and holdthe draw-bar l) by being bent downward at right angles and enterin ahole drilled through the said bar or by other equally suitable means.

I attach to the forward and lower point m of the plow a an adjListing-chain t, which passes upward and is confined at its upper end tothe draw-bar b in such manner that it can easily be lengthened orshortened as occasion requires. The object of this adjusting-chain tisto regulate the cutting depth of the point of the plow.

\Vithin the body of the plow a and parallel with the rear cross-bar 7cis rigidly secured a cross-piece y, to which is pivoted at its centerthe axle i, carrying wheelsff, projecting below the bottom plane of theplow. The whole weight of the latter in operation is carried upon thewheels ff, and they serve to guide and hold the position of the plowagainst lateral strain.

Handles g and g attached to the axle 6, extend upward and over thecross-bar 7.: to a sufficient height to accommodate the driver, and theyare adapted to engage in notches cut in said cross-bar 7a, to rigidlyhold them in a set position and prevent the strain in guiding fromcoming entirely upon the drivers arms.

\Vith the draw-bar b, in the position shown in Fig. 1 of the drawings,at the left side of the point of the plow and parallel with the rightside of the latter, the wheels ff should be set parallel with thelast-mentioned side by moving the handles 9 g to the right and droppingthem in the notches cut in the crossbar it to receive them. Now, as thedraft is from the rear portion of the plow and the whole weight of thelatter rests upon the wheels ff, the point m is adjusted to out acertain depth by taking up the adj ustingchain 2, and the gage-bar 6serves to hold the draw-bar Z) in position. Taking this position it cannow be readily understood that in drawing the plow forward all snow inits path will be thrown from the right toward the left, the side 1)casting the furrow, and its opposite side will simply aid in holding theplow steady against the wall cut by the point. The wheels f f projectingbelow the bottom of the plow, assist in receiving the lateral strainborne against the side p and serve to steady the machine.

shaped plow, of the draw-bar Z), the cross-bar 7a, and the gage-bare,the draw-bar being pivoted to the cross-bar, substantially as shown anddescribed.

2. The combination of the plow and the draw-bar pivoted at the center ofthe crossbar, the thills attached to forward end of the draw-bar andbraced thereto, as described, and the adjusting-chain t, connecting thepoint of the plow to the draw-bar, substantially as set fortlr 3. Thecombination, with the plow, of the wheels ff, mounted upon axle "i, saidaxle swiveling on acentral pivot in the bar y, said axle being providedwith the arms g g, and

the said wheels being adapted to revolve be low the bottom plane of theplow and parallel with the draw-bar, substantially as shown anddescribed.

.4. The combination, with the plow, of the rear cross'-bar, the draw-barpivoted centrally thereto adjusted and held laterally by the gage-bar e,and vertically by adjusting-chain t, the wheels revolving below bottomplane of plow and provided with the guiding-handles, whereby the plowmay be reversed to throw the snow to right or left, and in either casemay be directed to follow the line of draft, substantially as shown, andfor the purpose set forth and described.

In testimony that I claim the foregoing I have hereunto set my hand.

IRVING OSGOOD.
